OKX Announces Adjustment to Minimum Price Precision for Spot, Margin, and Perpetual Contracts

·

To enhance market liquidity and improve trading experience, OKX will adjust the minimum price precision for selected spot/margin and perpetual contract trading pairs on March 5, 2025, from 2:00 PM to 6:00 PM (UTC+8). This update aims to align pricing granularity with evolving market dynamics and ensure smoother execution across high-volatility and emerging digital assets.

The adjustment includes two types of changes:

All changes are designed to support long-term scalability, reduce rounding errors, and improve order book efficiency.

Adjustments with Temporary Trading Pause (Reduced Precision)

For the following trading pairs, the minimum price precision will be reduced, meaning prices will be quoted in larger increments. During this transition, each pair will experience a 2-minute trading suspension to ensure system stability.

Spot Trading

Note: During the pause, users cannot place or cancel orders, add margin, or transfer funds for the affected pairs. All other trading activities remain unaffected.

Adjustments Without Trading Interruption (Increased Precision)

These pairs will see increased price precision, allowing for finer price steps and tighter spreads. No downtime is required.

Perpetual Contracts

Spot Trading

Multiple ETHFI, GOAL, GOAT, RON, SLERF, ZK, XR, ZERO, XRP/BRL, and stablecoin pairs (e.g., USDC/SGD, USDT/SGD) will also receive enhanced precision — particularly beneficial for algorithmic traders and arbitrageurs who rely on micro-price movements.

This upgrade supports deeper liquidity layers and enables more accurate price discovery, especially in fast-moving markets.

Risk Notice and Operational Impact

Trading Suspension for Reduced Precision Pairs

Other trading pairs continue normally.

Order and Position Handling Rules

1) Order Processing Rules

A. When Precision Is Reduced (e.g., from 4 to 2 decimals)

Only orders compliant with the new precision will survive.

👉 Explore advanced trading bots that auto-adapt to exchange rule changes like price precision updates.

B. When Precision Is Increased (e.g., from 2 to 4 decimals)

All active orders remain intact and unaffected.

2) Position and Historical Data Display Rules

For Reduced Precision (Coarser Steps)

For Increased Precision (Finer Steps)

All systems retain previous display logic — no rounding applied.

Special Notes for API Traders

API traders must ensure their systems align with new precision standards:

Developers should update their order formatting logic before March 5, especially for reduced-precision pairs.

Frequently Asked Questions (FAQ)

Q1: What does "minimum price precision" mean?
A: It’s the smallest increment by which a price can change. For example, if precision is ±$1, prices can only be $98, $99, $1_, etc., not $98.5.

Q2: Will my open positions be liquidated during the adjustment?
A: No — open positions are preserved. Only pricing display may change slightly due to rounding rules.

Q3: How do I know if my grid bot will stop working?
A: If any of its orders fall outside the new price step (e.g., placing $5 steps when min change is $1), those orders get canceled — triggering full strategy termination.

Q4: Can I still trade other pairs during the brief pause?
A: Yes — only the listed pairs are paused for exactly two minutes.

Q5: Do I need to manually update my API scripts?
A: Yes — while OKX truncates invalid decimals, relying on auto-correction risks mispricing. Update your code to match new steps.

Q6: Why is ZERO/USDT seeing increased precision?
A: Higher precision allows better tracking of low-volatility or micro-cap assets where tiny price shifts matter more.
